What should be the explosion protection rating of the instruments used in general fine chemical enterprises?
Thread Content
I would like to ask the experts: Our company is involved in the fine chemical industry, and we are planning to launch a new project. I would appreciate your advice on what grade of explosion-proof instrumentation should be chosen for this purpose Which one has a higher grade, the CT6 or the BT6? Does the instrument have a BT6 rating?
It seems like you haven’t yet understood the concept. It is recommended to refer to GB3836 and GB4208.
It mainly depends on the process media produced by your equipment; the electrical engineering team determines the explosion-proof zone classification, and then the instrumentation is selected accordingly. The protection level is determined based on the production environment; in environments that are not particularly harsh, the protection level is generally sufficient with no issues
Of course, the CT6 has a higher grade. The instrument of BT6 is not suitable for environments with highly hazardous gases, such as acetylene. .
Thank you very much for the recommendation. I know absolutely nothing about explosion-proof protection, and I can’t even understand some of the information I found online. I’m really grateful for your recommendations! Thank you so much!

Typical choices: not lower than Ex d IIC T4 or E*a IIC T4; the protection rating should be at least IP65, but this also depends on factors such as the flammable substances present in the air.
